摘要： The concentration of alkali metal hydroxide contaminants in solutions of alkali metal alkoxides in alcohols is reduced to below about 0.1 percent by adding an alkyl alkanoate ester. For example, a solution of sodium methoxide in methanol containing about 0.04 percent sodium hydroxide was obtained by adding a small amount of methyl acetate. The alkali metal alkanoate salt formed as a by-product does not deleteriously affect most uses of such solutions.

摘要： The invention is a method for separating one or more polar liquids from one or more non-polar liquids which comprises the following steps. First, contacting a mixture comprising one or more polar liquids and one or more non-polar liquids with one side of a membrane comprising a polymer of a perfluorosulfonic acid, or metal salt thereof, which is adapted for selective permeation of the polar liquids over the non-polar liquids under conditions such that the polar liquids selectively permeate through the membrane. Second, passing a desiccant fluid by, pulling a vacuum on, or a combination thereof, the other side of the membrane, under conditions such that the polar liquids which have permeated through the membrane are carried away from the membrane. Third, removing the fluid desiccant containing the permeated polar liquids or the permeated polar liquids wherein a vacuum is used, from the vicinity of the membrane. Fourth, removing the non-polar liquids from the vicinity of the membrane.Another aspect of this invention is a novel hollow fiber membrane device useful for performing a preferred mode of the above-described method.This method allows the removal of one or more polar liquids which are dissolved in or entrained in one or more non-polar liquids in a continuous manner which no shoft-term changeout required.

摘要： Essentially all of the H.sub.2 S in steam which also contains up to 30 ppmw of CO.sub.2 per ppmw of H.sub.2 S can be scrubbed from the steam with aqueous NaOH or Na.sub.2 CO.sub.3 without consuming more than about 4 mols of NaOH or 2 mols of Na.sub.2 CO.sub.3 per mol of H.sub.2 S and without consuming more than about 0.18 pounds of water per pound of steam scrubbed, if (1) the steam is scrubbed countercurrently in a tower containing a contacting means equivalent to at least 6 theoretical stages, (2) the sulfide species in the tower effluent are completely oxidized to sulfo species and (3) the oxidized effluent--less a bleed stream and plus water and base makeup--is recycled to the tower. If the steam is scrubbed in this manner before being introduced to the turbines in a power plant, the exhaust from the turbines can be vented to the atmosphere without further treatment. The method of the invention is particularly suited for use at the Geysers geothermal "steam" field in California.
摘要翻译：基本上所有的蒸汽中的H2S也含有高达30ppmw的CO2 / ppmw的H 2 S，可以用NaOH或Na 2 CO 3水溶液从蒸汽中洗涤，而不用每摩尔H 2 S消耗大于约4摩尔的NaOH或2摩尔的Na 2 CO 3，如果（1）在含有等于至少6个理论阶段的接触装置的塔中逆流洗涤蒸汽，则塔的流出物中的硫化物种类是（1）不消耗大于约0.18磅的水每磅蒸汽，完全氧化成磺基物质，（3）氧化流出物 - 一个排放流，再加上水和碱的补充 - 再循环到塔中。如果在被引入发电厂的涡轮机之前以这种方式洗涤蒸汽，则来自涡轮机的排气可以排放到大气中而不进一步处理。本发明的方法特别适用于加利福尼亚州的间歇泉地热“蒸汽”领域。

US4017120A Production of hot brines from liquid-dominated geothermal wells by gas-lifting 失效

摘要： Hot brines containing dissolved gases are produced from liquid-dominated geothermal wells by utilizing lift gases of essentially the same composition as said dissolved gases. The lift gas is separated from the produced brine and recycled. Heat is abstracted from the separated brine, which may be returned to the aquifer, processed for its mineral content or discarded. The gas lift is carried out under temperature and pressure conditions such that precipitation of minerals from the brine does not occur in the well bore. The problems which would result from the use of oxygen-containing and/or brine-soluble inert gases for the lifting operation are avoided. The problems attendant upon production of hot brines by pumping are also avoided.
摘要翻译：含有溶解气体的热盐水由液体主导的地热井通过利用与所述溶解气体基本相同组成的提升气体产生。提升气体与生产的盐水分离并回收。从分离的盐水中抽出热量，可以将其返回到含水层，对其含矿物质进行处理或丢弃。气体升温在温度和压力条件下进行，使得在井眼中不会发生来自盐水的矿物质的沉淀。避免了将含氧和/或盐水溶解的惰性气体用于提升操作所产生的问题。也避免了通过泵送生产热盐水的问题。
